Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioners, and specifically relates to a central air conditioner grille. Background Technique

[0002] The central air conditioner is composed of one or more cold and heat source systems and multiple air conditioning systems. Different from traditional refrigerant air conditioners (such as single units, VRVs), this system centrally processes air to meet comfort requirements. In order to prevent a large amount of dust from falling into the air outlet of the central air conditioner, a dust-proof grille is usually installed on the mounting plate. The installation process of the dust-proof grille is extremely cumbersome, increasing the work difficulty of workers and being inconvenient for users.

[0003] The utility model patent CN216011221U discloses a conveniently installed central air conditioner dust-proof grille, including a mounting plate and a dust-proof grille. The dust-proof grille is located on the front side of the mounting plate. Fixed blocks are fixedly connected to both sides of the mounting plate. A positioning component is arranged inside the fixed block. A control component is arranged on the side of the positioning component close to the dust-proof grille. Clamping blocks are arranged at the top and bottom of the fixed block.

[0004] Through the cooperation of the positioning rod, the positioning component and the control component, this utility model fixes the dust-proof grille on the mounting plate, which is relatively convenient compared with the traditional installation method. However, there is a lack of a positioning component during the installation process. Since most central air conditioners are installed on the ceiling, there is a lack of a positioning structure during installation. Installers need to align the positioning rods of the dust-proof grilles on both sides with the corresponding holes to accurately install, which undoubtedly increases the installation burden of installers and has low practicability.
